The escape latency and the number of errors were detected by the escape darkness experiment. The brain tissues of rats were taken, the activity of superoxide dismutase (SOD) was measured by xanthinase method, and the content of malondialdehyde (MDA) was measured by thiobarbituric acid method. Hematoxylin and eosin (HE) staining was used to observe the changes of cell structure. The expression of tau protein and its phosphorylation protein were detected by Western blotting. The data were analyzed by ANOVA and n t test.n Results:On the 18th day after trauma, the escape latency of rats in Angong Niuhuang pill low concentration group and Angong Niuhuang pill high concentration group was (227.65±21.46), (250.37±26.05) s respectively, which was significantly longer than that in trauma group [(174.09±34.13) s], and the number of errors were (1.95±0.63), (1.17±0.49) times respectively, which were significantly less than those in trauma group [(3.80±0.77) times, n t=22.039, 24.726, 12.404, 14.837, n P<0.05]. The improvement effect of Angong Niuhuang pill high concentration group was more obvious (n t=11.827, 6.720, n P<0.05). The SOD activity in the brain tissue of rats in the Angong Niuhuang pill low concentration group and the Angong Niuhuang pill high concentration group was (270.25±21.60), (314.97±23.14) U/mgpro respectively, which was significantly higher than in the trauma group [(128.71±19.23) U/mgpro] and MDA content was (8.51±0.94), (6.05±0.61) μmol/mgpro, which was significantly lower than in the trauma group [(11.74±1.20) μmol/mgpro,n t=20.731, 24.209, 7.527, 8.398, n P<0.05]. The improvement effect of Angong Niuhuang pill high concentration group was more obvious (n t=12.694, 5.352, n P<0.05). The expression levels of tau, p-tau S199, and p-tau S404 in the brain tissue of rats were 1.73±0.29, 0.93±0.11, 1.42±0.25 in the Angong Niuhuang pill low-concentration group, respectively, and in the Angong Niuhuang pill high-concentration group they were 1.05±0.17, 0.67±0.08, 0.95±0.18 respectively, which were significantly lower than those in the trauma group (n t=8.128, 9.631, 9.305, 13.520, 12.758, 11.207, n P<0.05). The improvement effect of Angong Niuhuang pill high concentration group was more obvious (n t=7.392, 5.813, 6.605, n P<0.05).n Conclusion:Angong Niuhuang pill can significantly improve the learning and memory ability of rats with traumatic brain injury, which may be related to the inhibition of oxygen free radical reaction and tau protein phosphorylation level.
